Rubber face heating method and system of pre-coated film laminating machine

Abstract

The invention relates to a rubber face heating method and system of a pre-coated film laminating machine and belongs to the technical field of pre-coated film laminating machines. According to the technical scheme, an adhering steel roller (5) and an adhering rubber roller (6) are arranged on a rack (11) of the film laminating machine in parallel in an up-and-down mode. The adhering rubber roller (6) is driven by a hydraulic cylinder (10). A finned tube heating system (4) is arranged on the adhering steel roller and an axial flow fan (3) is arranged on the finned tube heating system. The position adjacent to the adhering steel roller is provided with a bending roller (7). A first film expanding roller (2) is arranged between the bending roller and a film holding device (1). A second film expanding roller (8) and a third film expanding roller (9) are arranged at a pre-coated film outlet of the adhering steel roller. The finned tube heating system is composed of multiple finned tubes which are arranged in parallel and surround the upper portion of the adhering steel roller. According to the rubber face heating method and system of the pre-coated film laminating machine, glue on the pre-coated film is fully molten instantly, adhering between a pre-coated film and printed paper is firmer, the surface of the paper laminated with the film is brighter, and the film laminating speed can exceed 100 m per minute.

Description

technical field [0001] The invention relates to a method and system for heating the rubber surface of a pre-coating film laminating machine, and belongs to the technical field of pre-coating film laminating machine equipment. Background technique [0002] At present, the existing pre-coating film laminating machines on the market all use heat-conducting oil heating and a simple film-through release method, that is, the pre-coating film directly passes through the film spreading roller, bending roller, and then heats up after passing through the hot laminating steel roller. Pressure lamination, due to the short heating time of the pre-coated film on the surface of the laminating steel roller, the glue on the film cannot be completely melted. When the machine is running at high speed, the paper and film will not be bonded properly, and there will be white spots, which will affect the quality of the film.
